The gorgeous CLS sedan gets the AMG treatment with the introduction of the CLS63. A new 6.3L V-8 cranks out a massive 507-bhp, which even exceeds the output of the Dodge Viper's 8.3L V-10. A claimed 0-100 km/h (62 mph) time of 4.5 seconds, and a governed top speed of 250 km/h (155 mph) ensure that the CLS63 will live up to the AMG performance reputation. A paddle-shifter AMG SPEEDSHIFT 7G-TRONIC 7-speed automatic funnels power to the rear wheels. Mercedes-Benz adds a sophisticated semi-active sport suspension based on the AIRMATIC DC system with ADS II adaptive damping and composite front brakes to keep the CLS63 under control. Interior upgrades include an AMG steering wheel, sports seats, and Nappa leather upholstery.

What Changed:

The handsome CLS-Class benefits from powertrain changes for 2007. A 382 hp CLS550 model replaces last years CLS500. A 507 hp CLS63 AMG replaces the CLS55 AMG. The PRE-SAFE anticipatory safety system added to all CLS-Class models.
